"Porno Gil" is the name of the episode. Here is the money shot!

It was a "fake bush" and thanks to the wonderful commenters at AV CLUB, I've learned that a wig used for pubis is called a "Merkin." Bless you all!

I could feel the pit in my stomach growing larger and larger as I thought that Kim was actually going to join Jimmy when he propositioned her at HHM.

BEST. LAUGH. EVER.
